Hi fellow Lenovo owners,
I currently use a T420s and mostly very happy with it. There's one thing that I couldn't get to work to my satisfaction, and thats the built in webcam. It says when I ordered it that its "720p".
Thus far, I've been only able to capture 1280x720 vids @ ~10 fps (capture was set at 30fps), using virtualdub, recording to a ramdisk.
Using windows movie maker, I can only capture at 640x360, and I can't seem to find any settings or options that I can change to make it 720p.
Does anyone has any experience using the builtin webcam to record at 720p with higher than 10fps?

What if you try it in a brighter environment? Maybe it's on low light mode?
-
Were you able to record at 1280 x 720 @ 30fps under "bright" environments? What kind of software do you use? -
I just have a T400... for now. I also don't use my webcam except for occasional video calls; I have never tried recording something with it.

I have a T420 and I've noticed the same issue. I only get 7-8 fps when recording at 720p. My cpu usage is only around 10%, so maybe it's a driver issue?
-
so does anyone get good frame rates at 720p?
-
Hi mate, I've kinda figured out a way.
I could get 30fps @ 1280x720 by using mjpg.
Try using virtualdub, and choose "MJPG" as the colorspace/compression and 1280x720 as the output size.
If you don't have a SSD, try recording to a RAMDisk to avoid dropping frames.
Also, if you use virtualdub, choose the "hide display on capture" option to avoid dropping more frames. -
souldnt the gma3000 be able to do 1080p H264 encode/decode?
Recording 720p 30fps vids from T420/s webcam?
