flv vs mov- which file type is bigger?

which file type is bigger out of a flv vs mov- assuming the video is identical

which would be a bigger file in size flv or mov?

 

I think mov.

 

I think almost same, and also if you just change the extensions between them, it will be fine

 

You haven't told us what quality are you aiming for? If you choose FLV, you'll get lousy quality, but small in size. MOV is better quality, but bigger in size.

 

Its a reasonably meaningless comparison as both FLV and MOV can use different encoding types, each with its advantages and disadvantages, also different encoders can make a difference even with the same codec. So until you specify a codec you cant really compare.

I'm willing to bet that I can create a FLV smaller than a MOV and the other way around from the same video.

It all depends on what codec I use and what bit rate I'm aiming for, it also depends on the target audience and what's best for them, it would also depend if your doing single or multi pass on the file.

To give you an idea though, I encoded 2 files both from the same source

Source Windows Media VC-1 8MBit 1280x720 (the BioShock2 Teaser Trailer if your interested in seeing it) and it was 92.1MB

Both files have been encoded at 1Mbit at 1280x720, the only major difference in the two setups is the audio output.

1) FLV using the VP6 Codec (Flash 8)

11.4MB

2) MOV using the H.264 codec

13.8MB

So in this test FLV was smaller, although the MOV looked better quality. There were things I could have done to improve both outputs, but I just accepted the defaults for this test.

Usually .MOV files are bigger than Flash Video Format (.FLV)
FLV Videos can be big too, but better quality is MOV

Also that depends on decoder settings!

 

normally .MOV files will be bigger

 

JenniP is the only person to have posted a sensible and knowledgeable answer. You can have equal quality with an flv or a mov, it's down to the codec used and bitrate applied. As flash video and quicktime can both use h264, in that case quality for a given set of parameters (i.e frame rate, resolution, bitrate) would be very similar.

 

.mov is bigger and more quality

 

mov is bigger and flv is much better for streaming over the net as when you generate an FLV from Flash you are able to bundle in bandwidth detection to enable the video to stream and change quality depending on the end-users internet connection speed.

 

Do you know any that actually do that though active8?

I know of two that do this on video start up, one thats been doing it for near on a couple of years, and one thats only just added it, and only one that does it in stream (IE if your bandwidth decreases while you are watching something it changes bitrate mid stream).
