One feature I've wanted to try for a while was recording movies with Jnes. With video sharing websites like YouTube so prevelant and accessible, this kind of feature is particularly meaningful these days. I decided to take a simple approach to this implementing this for the next version, similar to other emulators.
The feature breaks down into a recording mode that captures and initial jnes save state and subsequently records input at each frame to file. The playback mode can obviously then restore this movie and play it to the screen. While playing a movie back you can capture this to an AVI File using compression codecs such as XviD and DivX with audio.
As some of you may know Ninja Gaiden is one of my favorite games, altho I'm not a big fan of the more recent Xbox versions unfortunately. As a sample of the output Jnes creates I decided to capture myself playing the first level of this below and then upload this to YouTube.
And there you have it, hope you enjoy watching me play. I think this feature is very cool and I know it's something quite a few people have been asking for a while. Let me know what you think.
"The feature breaks down into a recording mode that captures and initial jnes save state and subsequently records input at each frame to file."
So do you mean it makes a macro from when your playing and than plays it back from a save state afterwards to export it to a video? That would be pretty cool cause then people could try to make and edit macros to play a game perfectly and beat it in record time but also there are enough free 3rd party macro utilities that can do this if you don't plan to implement it. I think this is a great emulator already, and has all the main features someone would want and is very stable.
This would be great. Those avi files could be used in front ends like GameEx so that it would be alot easier to get video previews of your games instead of snap shots while you scroll through them. I know theres other apps that do it, but having it all in one emulator performing that function would be great.
First, thanks for the best emulator since Nesticle. Never had any problems playing games.
I do however, have an issue with the movie capture/playback. It appears it captured fine, and I can open and even dump to an AVI. BUT I can only see the files from browsing to the directory in the JNes. If I close JNES and try to find the movie with Explorer, its no where to be found.
I have already set up show hidden files & folders.
cool video you have there^^
but, i want to ask, how you record the video? it is in jmv format, how do i convert it, i google searched but so far i dint manage to find the solution><
thanks for your help^^
I seem to have a problem. I saved the video by recording then stopping the recording. However, I didn't save it to a save state, so whenever I try to play the video and convert it to an avi, it converts for the right amount of time, but the avi is just a recording of the start menu
Hey I made a movie of me beating Mega Man 1 without dying once. The entire playthrough is recorded and goes on for 40 minutes. When I tried to copy it to avi though it didn't work, it seems to fail at anything over 4 gigs. Is there any way to compress this into a file small enough so that I can post on youtube or share the file? Also do you have to play the entire movie back on jnes in order to capture it as an avi?
The only avi files I successfully converted, I noticed are just between like 3-5 minutes long. Is it only made for short videos?
I would use some video compression to workaround this limitation, if you are using XviD as your compressor try lowering the bit rate of the video, you can find a guide on how to do this in the help section
I've used a standard compression that's included in Windows XP, the movie was almost a hour long... the converting went wonderful!
I'm gonna try the DivX 6.9.2 compression as for the Hypercam 2 earlier, to see if the file size gets smaller. I've noticed by some huge videos that they didn't reached 1GB 30 minutes videos with some frame issues...
I have now a video that reached 1,5 GB 0_o the Gradius NES gameplay until loop 4, stage 2
I hope that the compressor will be accepted by Jnes, some of the compressers won't work
Hey I love the Jnes emulator! It plays all my mega man games without any problems. However, the only I have is when it comes to video recording. I am trying to record my playthroughs of the mega man classic games (1-6). Yesterday I tried to record MM 5 in 5 minute segments. The actual movie recording is fine, even the encoding part. It's just when I try to play the .avi fil with windows media player, I get a video with static lines (like when you don't get reception on your TV), but strangely the audio for the video works perfectly. I just can't SEE the video. I don't know what to do. Assistance would be greatly appreciated!
Gave it a glance - looks like some other people on Emutalk are trying to help as well, have a look. There is a guide on this site under the help section that shows how to use XviD and links to download it. I don't know of any issues with movie recording right now - you may also want to give a few different codecs a try to narrow down the issue.
The emulator may crash due to the video codec, if you use Xvid for example you have to close the statistics popup that Xvid Encoder launches otherwise it ends up crashing Jnes when I close the AVI recording context. If you have problems with Xvid I would recommend trying one of the other codecs such as Cinepak Radius which is included by default in Windows.
