Frage von Zizi:
I'm looking for a codec, the following criteria:
- Good performance
- Acceptable quality for a Resolutionvon 640x480
Should - on any system running (OSX, Vista 64, XP, 7, etc.)
- For Free
- Effective in fast movements
- Farbtreu
so far I have converted the Divx videos (out of Cam) with Indeo and then back to Divx in order to work smoothly with it.
Since the codec is very old and little more widespread and is used should be something new here!
An alternative would H264?
Which program would convert for the best?
Edit: I synonymous looking for a program where I can synchronize 2 asynchronous via videos or audio track can really only read the offset.
Antwort von tommyb:
Yes. That would be an alternative.
But the point of performance, unfortunately you'll have to sacrifice in order to fully enjoy the wonderful quality of the codec to be able to.
A good encoder would be in your case, x264. So you can directly create the MP4 file synonymous run on any system (provided that should any) Codec and Player.
PS: Indeo still comes from the last millennium, and was as effective as moving pictures were a bit rare. That was around 1995, around;)
Antwort von Zizi:
Ok thanks for the tip!
What I still think he should like to synonymous Result values frame by frame can be accurately controlled without long delays.
Is that possible with H264?
gibts any alternative to that?
Antwort von tommyb:
No, not really - that's when the GOP codec technology (Group of Pictures) anyway to use very critical.
If you can influence the length of the GOP, or the maximum distance between I-frames can change, then we recommend a distance of 10 or 15 frames. The smaller the distance, the faster the calculation of Zwischenframes.
The distance should be not only too small, otherwise the benefit of the whistle is the small size of modern codecs again.
From personal experience I would put to you the XviD codec to his heart. When an I-frame interval of 10 frames can be a fairly liquid durchjuckeln on a X2 4800 + in AMD (720p25). Higher values allow the system to stutter again.
h.264 would, moreover, then a fortiori the overkill;)
If it is purely related professionals edit and size is no problem, but the speed of decoding, it is recommended Huffyuv. The codec is lossless (where the spaces are not converted) and is one of the fastest (if not THE fastest) lossless codec of synonymous costs nothing. Compression is here but not as efficient, so you come to about 25% of the size that would have an uncompressed file.
In conjunction with a RAID 5 or 0 Huffyuv synonymous is suitable for weaker systems with smaller processors.
