Respectfully; I would contend that the praying to the saints is NOT idolatry. The gentleman in video, though I am sure is very much sincere, does in fact have some misconceptions regarding "Praying to the 'saints'."
Let me clarify, when Catholics say that they pray to the saints, what they are saying, is that they are "asking the saint to pray for them on their behalf." No where has this ever meant by Catholics to imply that we give them worship. In terminology, particularly of the English language, the verb "to pray," signifies or means, "to ask;" therefore, with such a meaning, prayer thus does not equivocate with "worship," particularly and most especially with the "Divine worship," that is due to God alone. To give Divine Worship or "Latria" to any creature" in the Holy Catholic Faith, constitutes idolatry and to give Latria to anyone other than God, in the Holy Catholic Faith, is not only forbidden by Sacred Sacred Scripture, but also, Sacred Tradition, and most especially by the Holy Catholic Church itself; the Catholic Church has not ever nor will ever approval of giving "latria" to another other one, than the Lord God himself alone. And that is Dogma in the Catholic faith, which cannot be contravened nor nullified for any Catholics.
Catholics, give the saints "veneration" or "honour" by honouring them as those whom God has made holy or "sanctified." This veneration is known in greek as "Doulia." Any Saint, or even the Blessed Virgin Mary is always ascribed "doulia" as rightfully they should be as God's Holy ones; with the Blessed Virgin Mary, honoured with the "highest form of honour" due that can or is afforded to any creature, that of "Hyper-doulia," or the "Highest amount of honouring." Keep in mind that is no the same thing as "Latria," which I will refer shortly."
Think then, good folks, do we not honour one another's parents, as the Lord God hath commanded? If you're answering in the affirmative, you'd be correct in doing so.
Likewise we do honour, mind you not divine worship, to the saints. Divine Worship, that is worship that is ascribed purely and due to God alone, is known as "Latria," roughly being "sacrificial worship." Now, Latria is due to God alone, and no others; not even the saints, and most especially not the Blessed Virgin Mary. "Latria" is offered to God alone, for were "Latria" offered to any thing or one other than God, such an act would in fact constitute "Idolatry."
To give you some further resources on the "Saints," and the "Blessed Virgin Mary" and the correct Catholic view on them; please refer to the following links:

Scripture Catholic - SAINTS AND INTERCESSORY PRAYER
Nota Bene:
Now, I recognize the apprehension, that any of you must feel or the antipathy towards anything remotely that hints of Catholicism; now, I should like to admonish you, to be open minded towards our Saviour Jesus Christ and follow His will and that of the Holy Ghost's. Now, also, let it be known, that the apologist who proliferates the apologetics in the video being from CARM, I would've expected as much. I am familiar with them and was a former member of their forum, having previously ascribed to Protestant theology with CARM's help, I too once believed as they do.
However, since I have grown in my faith, by the grace of God and the guidance of the Holy Ghost, the Blessed Trinity, has shown me that the light of faith and in HIS holy grace, has directed me unto the Catholic Church. Now, disagree as one may, it is by God's grace that I've seen in Holy Scripture and in Sacred Tradition of God [not "traditions of Men" but the faith given "hand by hand" or "handed-down" or "traditio"-ed, or given by "tradition" from the Holy Apostles themselves unto the present day: the Christian faith in the fullness of its wisdom, dignity, strength, and grace; that the "Holy Catholic Church" is indeed the Church that Christ gave and established and perpetuated by Christ's commanded by the Holy Apostles' commission and under the guardianship of the Holy Ghost that has been preserved today.
I wish you all the best.
Christ have mercy!

Additionally, for further clarification, let one remember and call to mind, that Holy Writ exhorts us to pray for one another, and that it is efficacious.
NOTA BENE:
Pray for one another on earth is known as "intercessory Prayer;" for in doing so, one "intercedes" so as to ask or "pray" on someone else behalf. Thus when St. Paul implores us in Holy Scripture to "pray for one another;" he is asking for the "Intercession" of other Christians on one anthers' behalf.
Now, with our brethren who have departed this life, and entered into the Heavenly Kingdom, we ask for their prayers unto God on our behalf, knowing, that any prayers or knowledge of prayers, is only made permissible by the allowance of the Divine Will of God.
So, the hearing of any prayer and the granting of petitions is only done by God, and through His Holy Grace. Therefore, were God, to say act through a man or a woman on earth, so as to heal or help some one; would we not then thank them and pray our Blessed Saviour for his mercy and the grace in which he sought fit to bestow on one's self through the instrument(s) of his human servants?
I would then believe the answer would be that of "Yes;" or in the "affirmative."
Let one ponder with this in mind and again be open to the prompting and guidance of the Holy Ghost. Please do diligently, and with the guidance of the Holy Ghost, refer to see the links, that I have provided, so as understand more fundamentally, what exactly this business of asking the "Saints to pray for us" is in Catholic belief. The links explain in a most clear manner, far better than I myself am able to convey or articulate the Catholic belief regard "the Intercession" or praying to the saints."
I implore you all to do so, for see the Holy Catholic Church through her own eyes, rather than those whose misconceptions about her, paint their views and obscure the reality of which here teachings actually are and constitute.
Lord have mercy!

Also, remember that in the court of monarchs and kings, and even in Christian courts, whether Protestant or Catholic, one would bow or kneel before one's king or queen as a sign of honour, respect, or "veneration." The mere act of kneeling or bowing before on another is not in of itself considered "worship;" as such necessistates the addition of giving "Latria" or "Divine worship" or "sacrificial worship" to the one being bowed before or knelt before.
And remember as such, therefore, only Latria, properly "Divine worship that is 'sacrificial in nature'," can only and alone be offered to God; as such this is something believe that is doctrine----that divine worship can only be offered unto the Blessed Trinity alone.
