H264 on MOV container, small file – How To?
Hi There!
I’m looking for help with this case:
I must render my video on H264, in a MOV container, in HD, high quality. But the file always reach 5 GB or more…
I need it to be smaller, so I can put it on a DVD or on a FAT32 pendrive (which limits the data transference to 4GB).
I’m rendering from an Animation version of this video (almost uncompressed)
The bit rate and the keyframe frequence adjustments are on automatic
When I changed these (to 1000 and to “keyframe each 24 frames”) the quality went waaay low.Does anybody know what should I do to make this miracle happen?

[Ianah Maia] “When I changed these (to 1000 and to “keyframe each 24 frames”) the quality went waaay low.
“The two sliders you’re mentioning tend to be the key compression settings, which means you may want to change other factors:
– Frame RATE (from 30fps to 15fps, e.g.)
– Frame SIZE (from 1920×1080 to 1280×720, or even 640×360)The second of these options is the most common approach when trying to get a good-looking compression at a smaller filesize. Depending on the footage, however, the first option can work as well (when there is little movement, e.g.).
Essentially, if you cut the image size in half, you reduce the pixel count by a factor of 4, which means (in theory) that your compression will be 4 times better! Cutting your frame rate in half will double the quality of the compression, because it only has half the frames to work with.

You didn’t mention the length or if it was in HD or not…
But try:
2500 for the Data rate.
Keyframe every 30
FrameRate matching your sequence.
Codec .h264
Quicktime container .mov

Thank you!
I tried just changing the bitrate to 40.000 and it worked!
Now the video is only 1,73GB😀
