My videos are blurry after i convert them to FLV format using total video converter,help?
3gp is not the best video format, mostly low quality. converting it will reduce the quality again, you can try to reduce the resolution (size of the picture) and increase the Bitrate, the amount of data that the video plays at. playing about with those setting will give you the best quality, but you will not make it better than the original.

What is the best video file format to download among FLV 240p, MP4 360p, WebM 360p, 3GP 240p?
240P and 360P indicate the resolution of the video, specifically its height. That isn’t a real indicator of quality.Data rate is the main factor. A higher data rate probably indicates higher quality. I say probably because there are many choices you can make when encoding a file other than data rate, that affect its quality. But, in most cases its the best indicator.Another important factor is the codec used to encode the video. For instance, mp4s typically use h.264 to encode a file. There’s a new codec h.265, also known as an High Efficiency Video Coding (HEVC) codec. In comparison to h.264, h.265 (HEVC) allows you to encode at about half the data rate of h.264 and end up with the same video quality.MP4, FLV, WebM and 3GP are containers that hold files made with various codecs like h.264, h.265, VP 8 & 9, etc. I believe 3GP is an older format.There’s a free program called MediaInfo. It works on Macs. I’m not sure about PCs. When you open a video file with it, it tells you the codec, resolution, frame rate, data rate and more. The file with the highest data rate is probably the best quality.If you can’t use MediaInfo, when evaluating 2 files with the same resolution (360P, 480P, 720P, or 1080P, etc.), the one with the larger file size has higher data rate.
Which video format will take the least space?
Well, if you really want it directly If you take a video, Mp4 takes the most, followed by avi, followed by wmv, the lowest amount of space is taken up by flv's But, this is because the quality drops, the higher the quality, the larger the amount of space. Let me tell you something, if you want to reduce file sizes to amazingly small amounts, and keep their quality, you windows movie maker, import the video clip, put it on the timeline, then go to publish movie, compress to : And here's the best part ! YOU CAN REDUCE IT TO ANY SIZE YOU LIKE AND THE QUALITY REMAINS THE SAME! Hope this helped ^_^ If this isn't direct enough, you can ask for more help at bloomwinxgirl@gmail.com
Which of the following video formats has the smallest file size .mov, .mpg, .mpeg, .avi, .wmv, .mp4, and .m4v?
The file suffix has nothing to do with the file size. In fact, the mov, avi, and wmv suffixes describe the container format and don’t give you any information about how the media inside the container is encoded. For example: ‘mp4’ signifies a ‘mov’ file where the data is encoded per the MPEG-4 specifications (most usually AVC/h.264); it’s a mov file, so one can just change the suffix to ‘mov’ and it’s a valid QuickTime file (note: the QuickTime spec supports many features not included in the MPEG specifications, so every MP4 is a QuickTime file, but not every MOV is a valid MP4 file, even if the content is h.264 encoded).The size of the file is the duration of the content times the bitrate (number of bits used to represent 1 second of video). This is generally a tunable parameter for video encoding.Different codecs offer different levels of video compression. H.264 is one of the best as far as widest support, and h.265 is the best for compression ratio (though less widely supported). Both can be stored in MOV, WMV, and MP4 containers, though MP4 is the preferred container.MPEG generally indicates that the contents are encoded per the MPEG-1 or MPEG-2 specification. This older specification covers less efficient compression than the newer MPEG-4 spec, so the compression ratio is lower.AVI has some technical issues regarding newer codecs, like h.264, which use bi-directional frames (B-frames), so AVI typically uses older and less efficient codecs.WMV and MOV can contain just about anything.
How do you choose between MP4 or MKV format?
“Better” implies that you have criteria for comparison — but you didn’t state what those criteria might be.MKV and MP4 are container formats. MKV more or less permits any sort of audio and video streams to be in the container. MP4 is specified by the MPEG format and uses a simplified version of Apple’s Quicktime as the container and constrains the codecs used to those specified by the MPEG standard.As far as container format features go, QuickTime > Matroska > MP4.As far as container format support by other software and players goes, MP4 >> QuickTime > Matroska (in commercial applications, QuickTime is more widely supported, and open-source Matroska might have a slight edge).As far as container format codec support goes, Matroska >> QuickTime > MP4. Matroska was explicitly designed to be a universal container and support content in any encoding. The practical problem, of course, is that you can store content in encodings that other people don’t have a decoder for. QuickTime technically also supports any sort of streams like Matroska, but the spec only mentions about 20 video and 12 audio codecs, so anything outside of those you can’t expect to work in situations where QuickTime is used (in fact, a few of the more obscure codecs aren’t so well supported outside macOS). On the other hand, MP4 is quite restrictive, but that restriction is also an asset because something that deals with MP4 is going to support each codec (up to some complexity profile).As far as quality of quality of the content, that’s defined by the codecs used in the container and not the container itself. Matroska, MP4, and QuickTime can all contain HEVC (h.265) content, which is the best you’ll find today. In practice, h.264 is the one for which there’s the most support (due primarily to patent licensing issues) and all of the containers deal with h.264 just fine.So, which is better is going to depend dramatically on your criteria.
How do I convert videos by reducing file size for whatsapp sharing?
I always use Reviewstown Video Converter ( Reviewstown Free Online Video Converter ) to convert video for whatsapp sharing. It's a free web-based application to convert videos, you don't have to download and install anything. You just need to click ‘select files to start’ and import your video, choose avi or mp4 video as output format, and then click convert, that’s all. As I know, MP4 can keep video quality with smaller file size, and it’s compatible with whatsapp.
Video in AVI format takes forever to upload - should I convert it?
You did not define "small". Data is data. Uploading a file should not matter if it is AVI or DOC or PPT or whatever file type. AVI is merely an "envelope" holding the video. The video file information in that AVI envelope can be lightly compressed (large file size) resulting in better video quality or very compressed (small file size) resulting in reduced video quality - and lots of steps in between. If video quality is not important, just compress the video more in that AVI envilope. I have found: 1) "Medium" quality is good enough for YouTube. 2) Upload does not take so long - but YouTube's processing takes a longer than the upload time. There is nothing you can do to change the processing time and this is unrelated to the file-type uploaded. 3) There are certain times that are busier than others, but that seems to change and is not predictable. 4) If upload time was indeed the "long wait" what you have not shared with us is how your computer is connected to the internet. It is possible that the slow internet connection took longer than you wanted. The resolution is to get a faster internet connection. Since you did not tell us anything about the actual size of the video file or the internet connection used - or where the process took the time, we actually do not have enough information to provide you detailed assistance to fix what may not be broken.
How to check the total size of a youtube video i am going to watch?
Well This is very easy. there is no straightforward way, so you can find out by to TOTAL MINUTES showing at the YouTube's Player. there are 2 video formats YouTube is showing to you: low/regular-quality videos are encoded with FLV encoder. you can use firefox+downloadhelper addon to download a non-copyright- protected video. check the file size and length (time): lets say it's about 3.53 mb, (megabyte) = 1,024 * (kilobyte) so thats 3,614.72 kb. also lets say it's length is about 2 minutes and 40 seconds (---- (minute) = 60 * (second) ------) so total of 160 seconds. so let do some fraction action :) 3,614.72 kb. / 160 seconds ~~~~~~~ is about 23 kb per second now you got a roughly measurement. open a new video at YouTube, let us say its about 4 minutes -> 240 seconds multiple by 23 is about 5520 part 1024 is 5.39mb and this is the estimated size ! (the HD is MP4 encode, use same calculation as before..) you can do the same calculation on the HD version the video files, there the video has much more details so the file size will be bigger, with same amount of time (video length)- for example of a video that is having regular and HD version. once you got the rate you can know any video's size. this is possible because, although there ARE several ways and qualities for video encoding, youtube uses the same settings (FLV/MP4).

Assuming file sizes are the same, what format has the best quality video, MKV, MP4, or AVI?
The short answer is: it basically doesn't matter. What determines the quality of a video is the codec (h.264, MJPEG, ProRes, Cineform, etc.) and compression settings used, not the container format (.avi, .mov, .mp4, .mkv, etc.). The only impact the container format can have on quality is that it may or may not support a particular codec. For example, ProRes is only supported by a Quicktime container.On the other hand, many codecs can be used with multiple container formats. Cineform can be wrapped in either a .AVI or .MOV container, and (outside of the container-specific code) will literally be the same video data inside. You can even "re-wrap" the video from one container format to another without recompressing.Back in my anime fan-sub watching days, releases would often be better quality when in an .mkv format, but that was mainly because more technically proficient fansub groups liked it. The only exception to this is when a variable framerate video was used. IMHO, this is only useful when you have animation, since some sections (like the credits) were clearly animated at 29.97fps, but the rest of the show was clearly animated at 23.976fps. It was all broadcast at 29.97, but for smaller filesize/better quality at lower bitrates/smoother playback, the different sections of the fansub were encoded at different framerates.Looking at Wikipedia, I notice that now a bunch of other container formats support variable framerate, but I have never (to my knowledge) seen it used anywhere outside of fansub releases. People generally just pick a framerate and stick with it.Support for other features, like bundled optional subtitles and multiple audio tracks, can also vary by container format.
