Video Game Frame Rates
I recently posted this question on Youtube under tbritton33's video "Best Settings for CamStudio to Sync Audio and Video."
Hi tbritton33,
Can you tell me what's the minimum frame rate per second I should use to record SNES games? I will like to keep my file size to the minimum. Is 10 fps enough, or is it too little? 20fps? Keep in mind that this is is a SNES game, so I don't know if it changes much in terms of determining the lowest fps I should use. High fps also slows down the game, so the lower I go, the better, therefore, my question on what's the lowest fps I should use for a SNES game. Thanks for your help!

There is no "lowest" acceptable fps setting - go with what looks good by doing some tests. Just keep the "Capture Frames Every" setting multiplied times the Playback rate equal to 1000, and set "Use MCI to Record" in the audio settings, and you should be OK. I think CFE 50 PBR 20 looks fine for games, but CFE 100 PBR 10 seems a little too choppy for them (that's fine for tutorials, but just looks jerky on games). But your machine's limitations may dictate what you can do. Test!

*watches test video with 10fps*
Yeah, that is a little too jerky...
I just go for the highest quality and still get small videos with Xvid. The sound will eat up the most filespace now - so try that MSADPCM item at 44.1 mono, perhaps (to preserve the sync).
The slider on the "CamStudio Video Options" page only affects a few codecs (like Microsoft Video One, for instance). I'm not sure it affects Xvid since it has its own quality slider (which I set all the way to the left at 1 and still get small vids!)
Terry
The quality slider has absolutely no effect on CamStudio Lossles (nor on Lagarith Lossless) as their quality is always, well, lossless!
Xvid has its own quality slider, so that is the one used in that codec.
I'm not sure about Huffyuv or the Intel codecs...
It definitely has an effect on Microsoft Video One - 70 is the absolute lowest I would ever set that one to.
You'll just have to experiment with the same content. Perhaps record a lossles codec video, then record playback of that on a media player with auto-repeat turned on and "Automatically Stop Recording" set to so many seconds (300 seconds=5 minutes). Then watch your file sizes and compare. Do some with sound, some with sound off, and try the different sound codecs (Have "Use MCI to Record" checked at first, but then give MS ADPCM a try with "Use MCI to Record" unchecked).
This way you'll have a test bed to compare apples with apples by always having the same material in each comparison.
Terry
Okay, last video-related question, and this one is directly from the "lossless codec" forum-
Not audio related, but still one of those what-do-you-recommend questions, I currently have " set key frames every " to 200. Is that okay, or should I set it lower (again, this deals with trying to get the smallest size possible, so if I should lower it, what's the highest you recommend it to be?)
(Hopefully you wouldn't have replied to the other one by the time you see this, it it's a direct copy-and-paste)
Heh - Beat ya! http://camstudio.org/forum/discussion/676/lossless-codec-settings#Item_7

Now I have another question-When I switch the monitor to 16 Bit, CamStudio still says it's recording in "32 iBits". Is there a way to make CamStudio record in 16 Bits?
The question about the "kHz" still remains, though. Thanks for your help!
Yeah, you have to re-start CamStudio to see the change in display bit-depth...
I'd suggest sticking with 22kHz, MSADPCM 4-bit mono, with "Use MCI to Record" UN-checked. Do a ten minute test and then perform the reading-while-typing test I show at the end of the XP sync video.

If your sync stinks :-) then revert to "Use MCI to Record" and live with the large file size, I suppose. But I've seen that MSADPCM work perfectly, so I don't foresee you having any problems with it either.
Terry
Anything goes if it works! I'd double-check the sync stays tight with a 10-minute recording like I show at the end of my sync video. Wasn't MSADPCM adequate? It seemed to exhibit good sync.

If you can, watch it and can you give me some suggestions? It's the first video under the upload list.
Cool - where did you get GSM?
Nice video test! Too bad you can't go a little larger! (heh... file size joke... I know you won't go larger!)
Terry
Windows Media Player told me I have the Microsoft GSM 6.10 Audio CODEC installed, but I couldn't see it in CamStudio's drop-downs.
UNTIL, that is, I started searching and tried a bunch of kHz options. GSM only appears in the mono ones.
Cool - I have a new codec to play around with!
Thanks!
Terry
Well, I'm definitely happy to give some knowledge back at you!
By the way, I forget to mention that MS ADPCM does do stereo at 22KHz. See if that works!
Terry
Two screen dimensions translate into HD at YouTube: 1280X720 and 960X720 (4:3 aspect ratio, but appears in their 16:9 box).
If using Sizer with the Window region setting in 2.6b, remember to reduce the setting by one pixel each way to make up for the one-pixel-added bug (that is soon to be squashed) in 2.6b. So, 1279X719 or 959X719 configured in Sizer.
The "Fixed Region" settings do not need this finagling.
Terry
Furthermore, I found out that it's no use doing 32-bit, after all, it plays 16-bit games only!
"Use MCI to Record" uses the system audio format, which is CD quality, 16-bit, 44.1kHz. It skips compression and recording format (mono vs. stereo) according to what I've been told (and the file sizes are huge, so I think they are right!)
To use mono, un-check "Use MCI to Record", select the recording format but set it at 16-bit, 44.1kHz mono. 22kHz might work, but test for lagging. Make certain either PCM, MSADPCM or GSM 6.1 (for mono only) are selected as the compression type.
That has not been lagging, according to reports.
