Lossless Stuff

[Rapture**]

So I've got this problem...


Yesterday I finished segmenting of my footage for my next vid,and now I have this little problem - PC plays back my rendered footage too slowly,and that affects my editing,it's very hard to sync up! My clips are in Lagarith codec .avi format files.

I tried rendering a little clip with different codecs to check out if it's just my pc is too slow.. So here are statistics of my check versions :

My main system statistics :

AMD Athlon 3200+
768 MB of RAM DDR
80 GB Internal Hitachi HDD + 160 GB Internal Hitachi HDD
Nvidia GeForce 6600GT

I guess that's enough of my pc.

Now,my problem is with playback of those video files - Version 1,2 and 4 plays perfectly,but Version 3 (Lagarith) - plays too slowly. Huffy,is higher kbps,and much bigger file (~2x),so I thought it would give me more problems than Lagarith. If anyone knows how to solve this,that is to make Lagarith play back normally,just as every other version,I would very appreciate that.

I was under the impression lagarith

Playback performance in Premiere Pro (my target application):

Raw: Plays realtime (barely — the data rate is 30MB/s)

HuffYUV: Plays realtime.

Lagarith: Plays slowly (non-realtime).

MUS: Crashed Premiere Pro Played slowly (non-realtime) in VirtualDub.

So I guess there is no way out of this situation?..

[Shazzy]

if it's just my pc is too slow..

Yep..

For me, Lagarith tends to encode at about half the speed Huffyuv does. Additionally, the decode speed is slower than the encode speed; this is due to the nature of Arithmetic compression and the prediction algorithm.

Damn

[ffxdean]

whats is your Processors speed (in GHz or MHz).

I have a similar computer than yours (although alot worse: AMD 2400+ Athlon XP 2.0Ghz, 192MB RAM, GeForce4 64mb Integrated Graphics, 200GB Hard Drive 7200RPM

I tried using Lagarith and Huffman. I never had any playback issues.

unless you have background programs? for example having Adobe premiure along with windows media player playing 3GB of a 5min video will cause those symtoms you are having.

[Zarxrax]

Is it that your previews in premiere are slow? Just use a faster preview codec.

I'm using Vegas 5.0 >.>



My Processor speed is : AMD 3200+ (those 3200 are just for show,since system information says that my pc is only 2500 GHz) 7200 RPM

Damn that edit button,never there when I need it!

Anyway,it's not just in Vegas,playback is same even in VLC,MPC and Media Player itself..
