The MPEG-4 codec, which is basically a codec, shows a moderate quality due to the codec characteristics, but it is suitable for recording on low and medium-sized computers, and has a good software compatibility (playable in some video players) without using a hardware encoder. It is set by default.
If you have an NVIDIA graphics card (GTX Desktop 600 or higher or GTX 650M or higher for a laptop) or have high CPU performance, you can use NVENC H.264 encoder or Open H.264 encoder to record video quality. There is.
Click the Codec button in the Ocam main window as shown below and select Nvidia NVENC H.264 (if your graphics card does not support it, it will fail with an error if you start recording.) Or Open H.264 codec to record. Do it.
For the Open H.264 codec, the best video quality is obtained when the Recording-Normal-Quality is set to Very High in the following settings. (For NVIDIA NVENC H.264 codec, the following settings are not affected. You can change the settings in Codec-Hardware Encoder Settings in the Ocam main window.)
* In case of Open H.264 codec, the picture quality is good when the quality is set to very high, but it consumes a lot of CPU, so it may drop a lot of frames when recording a game, so we recommend using MPEG-4 codec if performance is not supported. .
* Since Nvidia NVENC codec is a hardware encoder, there is almost no frame drop than any built-in codec of OCAM for game recording, and it has the best recording performance, so it is best to use NVENC codec if the graphics card supports it.
* Using Nvidia NVENC codec, some games use a lot of GPU memory, but it also uses a lot of GPU memory for encoding, so recording may fail if there is not enough GPU memory.
* In the picture above, MP4 container is used. It can be used in MKV, M4A, MOV, and AVI containers.
How to improve sound quality
oCam is basically
I am using AAC audio codec (192 kbps).
To change the sample code or bit rate of an audio codec, click the Codec button in Ocam's main window, then click Set Audio Codec.
Then the following window will appear.
As shown in the figure above, the supported audio codecs support AAC, MP3, MP2, WMA, and Flac.
I personally recommend using the most widely used and compatible AAC codec.
You can improve the sound quality by changing the bit rate or sample rate.
For AAC codec, the supported bitrate is up to 512kbps and the sample rate is up to 96000khz.
You can use Flac codec to record losslessly, but recording file size can be large.
To change the audio codec you want to record, click the codec button of Ocam and select the container you want (for example, if you use mkv). Then select the codec with the audio codec you want in the container.
