During the most haunted days of the year, ghosts, vampires, zombies, witches, skeletons, devils, various sorts of monsters are all emerging in grand style. Lovely kids go in costume carrying with Jack-o’-lanterns from house to house, with the question of “Trick or treat?" to ask adults for candy. Halloween parties and parades are held here and there to celebrate our favorite holiday. All of these unusual scenes bring us a ton of fun, which are really worth shooting as precious memories.

As far as I know, lots of people use AVCHD camcorders to record everything Halloween related, and are willing to upload their special Halloween moments onto YouTube for sharing with everyone else. However, AVCHD camcorders save footages in the format of MTS and M2TS, which are out of the range of YouTube supported formats, they are .FLV, .MKV, .MOV, .WMV, .AVI, MPEG, .MP4, DivX, 3GP and .OGG, therefore, in order to upload MTS and M2TS video files onto YouTube successfully, you have to convert these files to YouTube compatible formats as above mentioned previously.
At the same time, one more thing you must notice, that is video files uploaded to YouTube by standard accounts are limited to 10 minutes in length and 2 GB in size and only partner account holders are permitted to upload videos longer than 10 minutes. That means you should compress the length and size of your footages to fit the two requirements. Take it easy, the following part will show you how to upload MTS/M2TS Halloween footages onto YouTube via Pavtube MTS/M2TS Converter in detail, just feel free to go on with this article.
Step 1: Download, install and launch Pavtube MTS/M2TS Converter
Step 2: Add MTS/M2TS files, select YouTube format and set save path
You can click on “Add” button to load MTS and M2TS files into this program, after that, hit the drop-down list of “Format” to choose a YouTube supported format, here I select FLV for instance. It is said that FLV should be a much better choice than other formats, as long as you limit the bit rate in not more than 320 kbps. In that case, the generated .FLV files will not be converted for the second time by YouTube’s encoders while uploading.
Meanwhile, if you want to combine all the MTS/M2TS files into one file, you can tick the checkbox of “Merge into one file” to realize this goal. Imagine you dislike using the save path set by default, you are able to specify a destination folder by yourself via clicking on the folder icon at the end of “Output”.

Step 3: Set advanced settings
In this step, you can compress the file of your Halloween footages, so as to meet the upload requirements of YouTube. Click on “Settings” button firstly, and then the following interface will pop up, which allows you to adjust video and audio parameters like aspect ratio, bit rate, frame rate, sample rate, etc. The smaller inserted figures will produce the smaller output file size, but accompanying with inferior video quality, so do remember making a balance between file size and video quality.

Step 4: Convert
As soon as all the above three steps are completed, and now you can press “Convert” button to begin conversion. The window below will show you the conversion info including conversion progress, time elapse, time left, generated file size as well as estimated file size. Particularly, the estimated file size will remind you if your output file size is not more than 2 GB. Otherwise, you should set the advanced settings again to fit the upload demands of YouTube. If you can't set the optimized settings accurately, try and match them as close as possible.
