I searched many internet sites but i can't handle this problem.
- 6 GB RAM
- 4* 2.4 GHz CPU
- 1 GB Radeon GPU
- SSD for System and Program
- HDD for Video footage
- Software: Adobe Premiere Pro CS6 with TotalCode Package.
- Captured with GoPro
- 29,97 fps
- MP4 Format
- data-rate 35140 kBit/s
- Clip 28s, 123 MB.
When i open this Clip within Adobe Premiere, create a sequence from the clip and try the preview the first 2 sec will play smooth and after that the video is jumping and stuttering or after running 2 sec the preview freezes. No effects applied. (CPU Usage ~50%, all cores)
So my Sequence settings are: Rovi TotalCode AVC-Intra 100, 1920*1080 30 fps Non-Drop-Frame-Timecode. No matter if i choose the TotalCode renderer or the Mecury Renderer. Video preview is set to AVC Intra-Class 100 1080 24p (or 30p or 60i - no difference). Video preview format makes no difference between full, 1/2 or 1/4.
I think because i created the sequence from the clip, there is no red/yellow/gren bar over the clip in the cutting window.
I get better results if i create a 720p sequence (for example: For editing 1280x720 AVCHD type video. Widescreen NTSC video (16:9 progressive). 29.97 fps 48kHz (16 bit) audio.). When i insert a clip and preview it the video stutters and jumps. But now i have the yellow bar. If i render the whole working area the preview plays smooth.
Okay - now i would say: its my fault, my PC has not enough power.
if i convert the MP4 via GoPro Studio to avi (Medium resolution) with the same specs (1920*1080*29,97) i got a 520 MB file (so roughly 4x the size of the original video).
When i use this clip instead of the MP4 the preview will play smooth (or nearly smooth) (CPU usage ~50%, all cores).
So Adobe Premiere has a problem with a data-rate of 35140 kBit/s but not with 151182 kBit/s on my PC? Hard to understand that this should be a performance issue...
I also tried to copy the clip to my SSD and start playing it, but nothing happens. Also tried to safe my project files on my SSD, not working.
I also tried to change the optimize rendern setting between Memory and Performance - nothing changed.
I saw this question: Adobe premiere is lagging in preview window -> Because of the mentioned AVI i don't think it has something to do with the data size.
Editing 1440p @ 47 FPS in Premiere Pro CS6 -> Much higher data-rate and video quality.
Adobe Premiere preview video lagging -> also talks about data rate (think this doesn't apply because of described avi/mp4 behavior)
Does anyone have some more ideas? Of course i could just convert 20 GB from mp4 to avi, but i'd like to safe this additional space on my hdd.
